Nginx: how to avoid logging of not found files - nginx

If would like to avoid logging of these usseless rows
Note: these are useless because our server is not running wordpress. So I'd like to simply avoid these lines in log file because we are monitoring error log files sizes and it cause false positive
[error] 22328#22328: *2090 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 77.89.13.110, server: , request: "GET /wp-admin.php HTTP/1.1", upstream: "fastcgi://unix:/run/php/php7.4-fpm.sock:", host: ""
how can I exclude these kind of rows?

I resolved adding two location inf my nginx config file, one for both of wp-admin and wp-login calls.
In these I simply disabled logging.
I cannot and do not want to disable logging of 404, because if user reach a 404 there I must understand what is wrong.

How to ban on specific 404 request, using NGinx

My server receives a lot of request for ".well-known/assetlinks.json". I think those request are from hackers.
Here what I get in the error file:
2022/03/07 20:16:02 [error] 44030#44030: *878180 open() "/somefolder/www/public/.well-known/assetlinks.json" failed (2: No such file or directory), client: 82.65.5.229, server: www.myserver.com, request: "GET /.well-known/assetlinks.json HTTP/1.1", host: "myserver.com"
How can I setup NGinx to ban the requester? Maybe a 2 hours ban...
I don't understand how to do it from the documentation.
This would not be a good idea especially as certain webcrawlers may be caught in this trap. It is recommended to leave the behaviour of most errors alone (except from custom error pages)

PayPal API causes 502 on nginx/fpm

I'm developing PayPal Adaptive Payments on one of my sites. Problems comes, when i deployed app, to server with NGINX+PHP-FPM. When i'm trying to process paypal payment, nginx throws 502 error.
18777#0: *711 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: xx.xx.xx.xx, server: www.domain.com, request: "GET /payment/5584 HTTP/1.1", upstream: "fastcgi://unix:/var/run/php-fpm.sock:", host: "domain.com", referrer: "http://domain.com/process/5584"
PHP-FPM are using socket file, to communicate with nginx. All other apps on server, was running correctly. PHP has json, curl and openssl enabled.
Have someone similar problem with paypal? Maybe some tips, or what to look for, when configuring nginx/fpm for using paypal api?
SOLVED
Uncommenting one line in php-fpm pool conf, solved first problem:
catch_workers_output = yes
Then i saw next error:
Message Unknown cipher in list: TLSv1
Removing:
CURLOPT_SSL_CIPHER_LIST => 'TLSv1'
From /sdk-core-php/lib/PPHttpConfig.php solved this problem, and now, my payments are running correctly :)

I have a mediawiki installation and an IPB installation. They both through up errors but this one error from mediawiki prevents me from posting semi-large articles. I have tried a lot of the solutions out there, adding catch_workers_output = yes, adjusting pm.* settings. Still not able to resolve this issue. I am coming to my wits end trying to figure this one out.

If the failure depends on size of the pages, it has to do with how much work the operation causes. My wild guess would be: increase the timeout (you currently have send_timeout 60s;).
It's easy for the parse time of a very long page to go over 60 seconds, especially if you're on a low power server, have not tuned performance or have enabled heavy parser extensions.
in my case it was that the php version of the project was different with the version of php I had been

502 Bad Gateway error with nginx and unicorn

I have nginx 1.4.1 and unicorn set up on centos - I am getting a 502 Bad Gateway error and my nginx logs shows this:
1 connect() to unix:/tmp/unicorn.pantry.sock failed (2: No such file or directory)
while connecting to upstream, client: 192.168.1.192, server: , request: "GET / HTTP/1.1",
upstream: "http://unix:/tmp/unicorn.pantry.sock:/", host: "192.168.1.30"
There is no /tmp/unicorn.pantry.sock file or directory. I am thinking that it might be a permission error and therefore the file can't be written if so who requires what permission - I have also read that I can create a tcp client
Also I don't understand where the 192.168.1.192 comes from
I just want to make it work How can I do it?
Ok I figured this out. I had unicorn.sock in my shared directory so I needed to point unix: to it

CUDA_CLIP Http Header?

While watching some log files the other day i saw a client suddenly start generating these error messages and for the life of me i cant figure out whats causing them.
2012/03/06 13:16:56 [info] 14212#0: *2018230 client sent invalid header line:
"CUDA_CLIIP: 10.3.68.20" while reading client request headers, client: 72.162.16.3,
server: <oursever.com>, request: "GET /images/101431.jpg HTTP/1.0", host: "<ourhost>",
referrer: "http://<ourserver.com>/<valid_url>"
This went on for more than 30 minutes before i dropped that ip in iptables. Fyi this is an nginx install.
The only information i could find online was this page:
http://nemesis.te-home.net/Projects/AdvOR-Help/
You probably just need to turn underscores_in_headers on;
